用一个直径为5 mm的胃-食管探头，在探头端部附近装有2个传感器，可用于测量32名正常人、5名肺气肿患者和3名呼吸肌异常患者的跨膜压。传感器在至少200 cmH 2 O压力下呈线性，并在正压和负压下提供相等的偏转。该方法显示出与使用2个球囊头端导管（1个在胃中，1个在食管中）的标准程序相当的结果。
A single gastric-esophageal probe, 5 mm in diameter, with 2 transducers mounted near the tip can be used to measure transdiaphragmatic pressure in 32 normal human subjects, 5 patients with emphysema and 3 patients with respiratory muscle abnormalities. The transducers are linear up to at least 200 cmH2O pressure and provide equal deflections for positive and negative pressures. The method is shown to give results comparable to the standard procedure using 2 balloon-tipped catheters, 1 in the stomach and 1 in the esophagus.
